Medtronic MiniMed 780G Insulin Pump and Accessories Analysis Report

Device Identification, Brand and Model Analysis

The main product and components shown in the visuals are advanced medical devices used for diabetes treatment and insulin management. As a result of detailed examinations, brand and model information has been identified as follows:

• Brand: Medtronic
• Main Device Model: MiniMed 780G Insulin Pump (Confirmed by inscriptions on the box and user manuals).
• Transmitter Model: Guardian Link (3) (Read from the label on the visual, REF: MMT-7911NA).
• Charger Model: Medtronic MiniMed Charger (Stated as REF: MMT-7715 on the label).

Areas of Use

This product set is typically used to ensure blood sugar regulation for individuals with Type 1 diabetes. The insulin pump provides continuous insulin infusion to the body, while the Guardian Link (3) transmitter transmits sensor data to the pump, enabling blood sugar level monitoring (Continuous Glucose Monitoring – CGM). The phrase “Software upgrade kit” in the visuals indicates that the device includes the necessary equipment for software updates or upgrading to a higher model.

Authenticity Status

Upon examining the Medtronic logos on the products, the font type of the labels, the arrangement of REF/SN codes, hologram details, and the quality of accessory packaging, the products are assessed to be Original Medtronic equipment. No visual findings indicating counterfeiting were observed.

Quantity Information

The total parts and set contents identified in the visuals are as follows:

• 1 MiniMed 780G Insulin Pump (inside a black silicone case).
• 1 Guardian Link (3) Transmitter.
• 1 Transmitter Charger.
• 1 MiniMed Reservoir Box (Reservoir).
• 1 Black box containing a System User Guide.
• 1 White sealed box containing a MiniMed 780G Software Upgrade Kit.
• 1 Quick-Set Infusion Set and Reservoir reference booklet.
• 3 Small plastic bags containing accessories/devices (Clip, USB adapter etc. visible).
• 1 Black protective belt clip/case piece (Worn).
• 1 White “GL3” labeled test/protection plug.

General Condition and State Analysis

The condition of the set varies among the parts:

• Boxed Products: The “It’s here! MiniMed 780G software upgrade kit” box is covered with transparent packaging (shrink wrap) and is in an unopened/new condition. Other boxes (User Guide and Reservoir), although opened, appear clean.
• Insulin Pump: The device is active and operational. However, there are traces resembling adhesive residues on its back and significant paint abrasions in the rear clip/slide slot. It is clearly visible that the device is used (second-hand).
• Case/Clip Accessory: The separate black piece (likely a belt clip or part of a case) shows very intense scratches, coating peeling, and signs of use.
• Transmitter and Charger: The transmitter’s surface is clean. The charger’s labels are legible, and its plastic casing is intact.

Physical Deformity and Cosmetic Examination

On the rear surface of the insulin pump’s main unit, next to and below the battery cover, there are dullness and residue marks resulting from previous use. Apart from the black case attached to the pump, the spare plastic piece next to it (the bottom piece in Image 3) shows very prominent peeling and whitening; this indicates that the piece has been exposed to mechanical friction for a long time. No deep scratch or crack that would impede usage has been detected on the device’s screen in the visual.

Electronics and Screen Analysis

The insulin pump (MiniMed 780G) is shown turned on in the visual:

• Screen: The color screen is functioning without issues. A glucose value of “100 mg/dL” is displayed. The time appears as “14:53”, and battery status and reservoir level icons are actively shown. The menu heading “Reservoir & Tubing” is legible. No pixel loss or screen burn was noticed in the visual.
• LED Indicator: When the Guardian Link (3) transmitter is plugged into the charging/test unit, its green LED light is on; this proves that the device is receiving power and is active.

Battery and Power Status

The pump has a battery level indicator, showing a green fill level. However, since the device operates with AA batteries, no comment can be made on internal battery performance. The transmitter has its own internal rechargeable battery; the green light indicates that the battery is at least holding a charge or is currently charging. The charger operates with “AAA” type batteries (understood from the rear cover structure).

Label and Serial Number Information

The following critical identifying information has been read from the rear surfaces and labels of the products:

• Insulin Pump:
  • SN (Serial No): NG2548811H
  • REF/CONF: M990175A001
• Charger:
  • REF: MMT-7715
  • SN: GT7986582N (Although it appears mixed with the transmitter, the codes located on the charger label along with the FCC ID have been analyzed). Note: Since the charger and transmitter are side-by-side, the specific serial number on the back of the charger should be traced from the codes related to MMT-7715, while the transmitter should be traced from the code specified below.
  • Address: Medtronic MiniMed, Northridge, CA 91325 USA
• Transmitter:
  • Model: Guardian Link (3)
  • REF: MMT-7911NA
  • FCC ID: OH27821

Accessories and Mechanical Components

No visual breakage has been detected in the mechanical components (keypad, battery cover, socket entries). The directional buttons on the pump appear intact. The red gasket on the battery cover is in place, which indicates an attempt to maintain insulation against liquid contact. The accessory bags are unopened.

Potential Malfunction Risks and Warnings

Since the electronic screens of the products are functioning, no mainboard malfunction is observed. However, the physical wear on the back of the device indicates heavy use of the product. The excessive wear of the plastic clip parts suggests a possibility of drops or impact history, but no related cracks have been observed on the device casing. Although the condition of the red gasket on the battery compartment cover appears good, water resistance should not be guaranteed as it is an old device. The “Reservoir & Tubing” alert is visible on the pump screen; this is not a malfunction but a standard procedure indicating that the set-up is required.
